Heart Rate Monitor Troubleshooting
Hand Held Heart Rate Does not Work
1. Place your hands on the handlebar HHHR
1
(Hand Held Heart Rate) hand held pulse
sensors, making full contact with both top and bottom pulse sensors for at least 15
seconds.
a. If the console displays the heart rate, no problem exists.
b. If the console does not display a heart rate, continue procedure.
2. Set the ON/OFFswitch to OFF, wait 10 seconds, then toggle the ON/OFF switch to ON.
Grasp the hand held HHHR pulse sensors for a minimum of 15 seconds.
a. If the console displays the heart rate, then the cycling the power reset the HHHR
processor and the issue is fixed.
b. If the HHHR does not function correctly, continue procedure.
3. Verify that the 4-pin handlebar pulse assembly input cable connector and the Power-
/Pulse signal cable connectors are correctly plugged into the HHHR PCA
2
board con-
nectors. Make sure that all pins fit properly into the connectors and that there are no
damaged or shorted pins.
a. If the cable connectors are damaged, replace the cable.
b. If the HHHR PCA connectors are damaged, replace the HHHR PCA board.
c. If the HHHR feature does not function correctly, continue procedure.
4. Verify the chassis ground cable is connected to the HHHR PCA board. Also verify the
ground cable is connected to the console weldment and provides a zero resistance
ground path to the chassis (a short, zero resistance to ground).
a. If the HHHR functions correctly, the issue is fixed.
b. If the HHHR does not function correctly, continue procedure.
5. GEN-06 treadmill only: Verify that there is a ferrite bead around the cable from the
HHHR board to the upper PCA. If missing, add the ferrite bead and verify HHHR oper-
ation. If this repair does not fix the issue, continue procedure.
6. Verify that the machine does not display a heart rate with only one hand grasping a
given left or right handlebar HHHR pulse sensor. This would indicate static damage,
and require replacement of the heart rate board.
7. Remove the left (top & lower) and right (top & lower) handlebar pulse sensor assem-
blies and verify that the hand pulse sensors and electrical connections are free of cor-
rosion and have good electrical contact.
a. If the pulse senors and/or electrical connection contacts have corrosion, replace
the corroded HHHR hand pulse assembly.
